Hummer Forums - Enthusiast Forum for Hummer Owners

I'm about ready to pull the trigger on new rims and tires and would appreciate some opinions and fitiment verification. Rims are eagle alloy series 079 Eagle Alloy Wheels#. 18x9 (-12 offset, 6 on 5.5).What is hubcentric? And are these hubcentric? Tires are Nitto Trail Grappler mt's. Nitto Tire - High Performance Tires for Car and Truck Enthusiasts 285/65/r18. (32.83" x 11.93" wide). Was also thinking maybe the 295/70/r18. (34.57x 11.73" wide) but I don't like the look of a tire taking up the entire wheel well. Love the look of this forum members truck but I don't want to have to do a shackle lift or crank the t-bars beyond the reccomended spec.
